matlab imread grayscale
The rgb2gray function converts RGB images to grayscale by eliminating the hue and saturation information while retaining the luminance. If you have Parallel Computing Toolbox™ installed, rgb2gray can perform this conversion on a GPU. newmap = rgb2gray( ma,A grayscale image (also called gray-scale, gray scale, or gray-level) is a data matrix whose values represent intensities within some range. ,A = imread( filename ) reads the image from the file specified by filename ....
